## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_page`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check whether a web page's Meta Pixel (Facebook Pixel) works: cookie consent, duplicate events, event IDs, the ad click ID (fbclid -> _fbc) and signs of server-side tracking. A browser in the EU visits the page twice. Reuses a result from the last 24 hours unless recheck is true. Waits for the result up to wait_seconds (a check takes 20 to 60 seconds); if it is still running, call get_report later.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_fix_guide`

- The name "get_fix_guide" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Step-by-step guide (Markdown) for fixing a problem the check found, for the site's platform when one exists (otherwise the general version). With consent_tool, returns the guide for wiring the Meta Pixel to that consent tool instead. Guides exist for: meta.fires_before_consent, meta.not_firing_after_consent, meta.duplicate_pixel, meta.missing_event_id, meta.fbc_not_set, and general.server_side_not_detected (setting up the Conversions API).
```

### `get_report`

- The name "get_report" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the result of a check by its report id or report link (https://ispixelworking.com/r/<id>): status, grade, problems with explanations and fix guide links, checklist. Reports are kept for 90 days.
```

### `list_findings`

- The name "list_findings" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every problem (finding) the check can report, with id, severity, title, explanation and whether a fix guide exists.
```
